The last time I bought new glasses, a few months ago, I went to a store and tried on a million different frames for like a half hour. By the end of my try-on montage, I had a pile of glasses set aside, yet I chose the first pair I tried on, the ones I spotted as soon as I walked in the store. I pointed this out to the worker, laughing, and he proceeded to say something so profound: He was like, "yeah, everyone does that. No one trusts that their first instinct was right".
Is that not jaw-dropping? Everyone does that? I carry this story around like a personal fable and now rec saving stress and time by going with your first instinct, it's literally probably right.
